Cloudflare outage on February 20, 2026
Summary
Cloudflare's BYOIP outage on February 20, 2026 was caused by a bug in the Addressing API automation that withdrew prefixes, resulting in about 1,100 prefixes being withdrawn and a 6-hour outage. The incident was not due to a cyberattack; Cloudflare outlines remediation focused on safer deployment, API standardization, and better separation of operational and configuration state to prevent recurrence.
